EVAR Technical Tip – Confirmation of Contralateral Limb Gate Cannulation Using a Moulding Balloon☆

Abstract 

Introduction

Accurate confirmation of cannulation of the shorter contralateral limb gate of an abdominal aortic endograft can be challenging. Catheter angiogram may not exclude all possible errors.

Report

Accurate contralateral cannulation can be confirmed by insertion of a moulding balloon over a stiff wire and gentle inflation of the moulding balloon across the contralateral gate of the main body component.

Discussion

The technique of using a moulding balloon to confirm accurate cannulation of the contralateral gate is a good method of eliminating doubt whilst maintaining a stable wire and catheter position.
